Is Your 2010 HUMMER H3 Stalling, Hesitating, or Refusing to Start?
If you’re dealing with frustrating fuel delivery problems in your HUMMER H3, a faulty Fuel System Control Module (FSCM) is a very likely culprit. This small but critical computer, also known as a fuel pump driver module, is responsible for managing the voltage sent to your fuel pump. When it fails, it can starve your engine of fuel, leading to a host of performance issues that can leave you stranded. I’ve seen this exact failure countless times in my 20+ years as a technician, often after a vehicle has been through a harsh winter where road salt and moisture have corroded the module’s electronics.

Real-World Diagnostics: A Story from the Shop
“A customer’s 2010 GMC Sierra 1500, which uses this identical module, came in on a tow truck last week. It would crank all day but wouldn’t start. The owner had already spent $500 replacing the in-tank fuel pump, assuming that was the problem. A quick scan showed code P069E (Fuel Pump Control Module Commanded OFF). We checked the module, located on the frame rail, and found it was heavily corroded. We swapped it with one of our pre-programmed units, and the truck fired up on the first try. He could have saved himself a lot of time and money by checking the FSCM first.”
Easy Installation for Your 2010 HUMMER H3 FSCM
You don’t need to be a master mechanic to replace this part. On the 2010 HUMMER H3, the FSCM is typically mounted on the rear frame, making it accessible. With basic hand tools, you can have this job done in under an hour.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FSCM mounted to the vehicle’s frame, usually near the spare tire area.
- Disconnect Connectors: Carefully press the release tabs and unplug the electrical connectors from the old module.
- Remove Old Module: Unbolt the old FSCM from the frame. These bolts may be rusty, so a little penetrating oil can help.
- Install New Module: Bolt your new, pre-programmed FSCM into place.
- Reconnect and Test: Plug the electrical connectors firmly into the new module and reconnect your battery. Turn the key to the ‘On’ position for a few seconds to let the system prime, then start your engine.
